what kind of times are you s2000 race car owners running at this track?? also any info about tires(brand, sizes) would be greatly appreciated. thanks.

 

There are a couple videos of thunderhill on this site for reference: http://www.gofastvideo.com/

I think most of the guys here agree Toyo RA-1's are the best track tire considering pace and longevity. If you're on stock suspension I'd do 205/55/16 front and 245/45/16 rear. With stiffer front sway bar go 225/50 front and stay 245/45 rear.

Oops, I just went to look for new vids and I guess there aren't any of S's at thunderhill. I thought there were??

 

thanks guys....ive seen a 2:03, which is pretty quick...how do you guys think an S2000 with about 275hp in some capable hands would do(were talking about a full race car on 3-ways)...looking at the 25 hour as a race we might enter.

 

What's the weight of the car?

 

And tires?

 

its under 2400 pounds

 

225 and 245 on 16's

 

With cyclone, I'm thinking 2:07's (assuming RA-1s). Your weight and HP should make up for RL's larger tires.
